Overview

The Fujifilm Sonosite LX and Sonosite PX Ultrasound Systems are advanced point-of-care ultrasound (POCUS) solutions designed to empower clinicians with immediate answers and enhanced diagnostic confidence at the bedside. Both systems feature Sonosite’s most advanced image clarity, enabling accurate visualization of anatomical details for a wide range of diagnostic and procedural applications. The Sonosite LX boasts the largest clinical display in the Sonosite portfolio, with an expansive touchscreen that extends, rotates, and tilts for optimal accessibility and collaborative viewing. It emphasizes a ‘heads-up workflow’ to improve time to diagnosis and treatment. The Sonosite PX offers a flexible, hybrid interface combining touch and physical controls, along with an adaptable horizontal-to-vertical work surface for optimal bedside ergonomics. A notable recent addition is the AI-powered PIV Assist feature, available on both LX and PX systems, which aids clinicians in vascular access planning by quickly identifying veins, differentiating arteries, and selecting optimal insertion sites. Both systems are built for durability, ease of use, and feature robust data security measures to protect patient information.

What Physicians Need to Know

DICOM Support & Standards
Full DICOM support (compliant with latest versions) for images, clips, and structured reports, including DICOM Store, Print, Modality Worklist, MPPS (Modality Performed Procedure Step), and Storage Commit.
PACS Integration Method
Seamless integration with PACS and other hospital information systems via full DICOM support and Ethernet connectivity. Also integrates with Sonosite Synchronicity workflow manager for managing patient and procedural data across clinical and administrative networks.
Reading Room Workflow Impact
Designed for optimized workflow with intuitive touchscreens and physical controls, customizable presets, and streamlined user interfaces to reduce touches and improve efficiency. Sonosite LX features a 'heads-up workflow' with an expansive clinical touchscreen display. Sonosite PX offers advanced calculation workflows. The AI-powered Sonosite Voice Assist enables hands-free control for critical functions, enhancing sterility and workflow efficiency.
AI Model Architecture (deep learning approach)
Features 'PIV Assist,' an AI-powered tool for peripheral IV access, offering real-time vessel identification, color-coded guidance for veins and arteries, and catheter-to-vein ratio (CVR) calculation. This feature was developed using tens of thousands of scan images. Sonosite Voice Assist is another AI-powered feature enabling hands-free system control.
FDA Clearance Pathway (510k/De Novo)
Both Sonosite LX and PX have received 510(k) clearance. Sonosite PX (K213763) and the entire POCUS portfolio, including PX, received 510(k) clearance for lung and cardiac imaging of COVID-19 patients. Sonosite LX (K233597) also received 510(k) clearance. The PIV Assist AI feature on both systems was cleared via 510(k) (K251106).

Frequently Asked Questions

The Sonosite LX and PX systems incorporate AI through features like PIV Assist, which provides real-time, color-coded guidance for peripheral intravenous access, identifying veins and arteries, and calculating the catheter-to-vein ratio. Additionally, Sonosite Voice Assist allows for hands-free control of key functions, streamlining procedures and maintaining a sterile environment.
While AI features like PIV Assist are designed to reduce cognitive load and enhance confidence, they are assistive tools and do not replace clinical judgment. AI relies on extensive data for its algorithms, meaning atypical conditions might not be as accurately identified. Physicians should always integrate AI guidance with their expertise and patient-specific clinical context.
Both Sonosite LX and PX systems are built with robust security features, including FIPS199, FIPS200, and NIST 800-53 compliance, secure boot-up, and FIPS140-2 data encryption for stored and in-transit data. Fujifilm Sonosite actively monitors for cybersecurity vulnerabilities and adheres to FDA regulations and the European Medical Device Directive (MDD).
The PIV Assist is Fujifilm Sonosite's first AI tool, focusing on vascular access, while other systems like Samsung's premium R20 offer a broader suite of over a dozen AI-powered tools for various applications including diagnostic assistance and workflow automation. Competitors such as Philips Lumify and GE Vscan Air also offer advanced portable solutions, though their specific AI features may vary.
New Sonosite PX systems can have list prices around $45,000 USD, with actual procurement prices ranging from $80,000 to $130,000 USD, while portable systems generally fall between $20,000 and $100,000. AI features like PIV Assist are offered as licensed add-ons, and transducers are sold separately, typically costing $3,000-$12,000 each. Annual service and maintenance contracts are an additional cost, usually 8-12% of the system's list price.
Both Sonosite LX and PX are designed with comprehensive connectivity options, including secure DICOM transfer, to facilitate seamless integration with EMR and PACS. This ensures that ultrasound images and reports, potentially enhanced by AI-generated insights, can be efficiently incorporated into a practice's existing workflow.
Fujifilm Sonosite has recently introduced PIV Assist as its first AI-powered feature, indicating a commitment to integrating AI into their POCUS solutions. While specific future roadmaps are not publicly detailed, their collaboration with institutions like Partners HealthCare suggests ongoing efforts to embed AI for enhanced image interpretation and automation, aiming to increase accessibility and diagnostic value.
